Quilted Styles Are Our Winter Activewear Staples

One of the keys to selecting winter-friendly activewear is to look for pieces that allow for warmth but leave the bulk at home. The Athleta Whisper Featherless Long Vest ($229) is a great example, with its lightweight, thermoregulated design that keeps the insulation without excess fabric or bulkiness. I'm already imagining this piece layered over my favorite tights and hoodie for winter hiking adventures.
